To make a electrical equipment multifunctional by Mitsubishi air circuit breakers which suitable for the main circuit protective device. The air circuit breakers have many advantages, that is, to realize the high reliability of switching performance, to extend the area of selective coordination due to expanding of the rated short-time withstand current, to be suitable for main circuit port.

Air Circuit Breakers (ACB)

• Air circuit breaker is a circuit breaker for the purpose of protecting low voltage circuit, mainly for energizing and cutting off high current.
• It is used as the master of a factory and building, and as a main circuit breaker of a ship, and it is possible to attach various accessories according to the purpose.
• We also have a draw-out installation method with high maintainability.

Electronic Trip Relay (ETR)

• Electronic Trip Relay trigger circuit outputs a trigger signal to energize the trip coil, when the CT detects the value exceeds the predetermined value.
